Today, a phone book delivery person traveled along South Schenley Avenue while tossing new phone books onto the front yards of the homes. The books were in a flimsy unsealed plastic bags.

People who work all day will arrive home after dark and won't see the phone book on their lawn. To make matters worse, it is supposed to snow overnight. The phone books will be covered with snow and the plastic bag will probably leak moisture onto the phone book.
